Hello, I'm using an version 2019 of the software and I'm facing a problem. The nodes only appears on the screen when they are selected. This is a problem, because when I create a node, it get lost on the workspace, invisible on the screen (When I was creating the node, I took care to click "fit model"). I realized the folowing test: I create two nodes (000) and (010), and selected "fit model". After that I selected "lines">"linear nodes">"node list" and holding Shift I made a selection of all the workspace. Doing that the nodes appeard in grey collor on the screen. Somebody can help me with this problem, please? Thanks in advance, Renato.
